Chapter 15, Problem 15.73AQAP

Interpretation Introduction

(a)

Interpretation:

The given electrolytic cell diagram needs to be completed and the electrode acting as anode needs to be determined.

Concept Introduction:

In the electrochemical cell, the reactions at cathode and anode occur due to difference in their reduction electrode potential value. The EMF of cell can be calculated with help of electrode reduction potential values. The reaction at each electrode is called as half reaction and combination of both half reaction gives the cell reaction of given electrochemical cell.
